About the Airtac SAI80 Standard Air Cylinder SAI80X950S
The AirTAC SAI80X950-S is a double-acting ISO 15552 profile cylinder engineered for substantial linear motion tasks. Delivering a robust 3518 N of push force at 0.7 MPa, this 80 mm bore unit is built to handle heavy loads across its 950 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes an integrated magnet (-S) for use with CMSE or DMSE reed switches, which seat neatly into the dual sensor grooves machined into both sides of the barrel. The standard carbon steel piston rod offers excellent tensile strength for industrial environments, while the adjustable air cushions at both ends absorb kinetic energy to protect end caps during high-speed cycles.

Where the Airtac SAI80 Standard Air Cylinder SAI80X950S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 950 mm gap in automated packaging lines, utilizing the 3518 N force at 0.7 MPa to overcome sliding friction.
Large Door Actuation
Opens and closes heavy industrial machine guarding doors or blast cabinet doors, relying on the adjustable air cushions to decelerate the 80 mm piston smoothly at stroke end.
Press Ejection Systems
Ejects finished parts from large stamping presses, where the integrated magnet (-S) triggers CMSE sensors to confirm part ejection to the PLC.
Is the Airtac SAI80 Standard Air Cylinder SAI80X950S the Right Cylinder?
Selecting this 80 mm bore cylinder makes sense when your application requires the 2513 N push force available at 0.5 MPa, stepping up from a 63 mm unit that provides 1559 N. If your system demands less than 2000 N, dropping to the 63 mm bore saves physical space and air consumption. Because this model features a 950 mm stroke, the extended rod is highly susceptible to bending under side loads; always utilize an external linear guide or a guided cylinder carriage to prevent premature rod-bearing wear and piston drift.
As a true ISO 15552 profile cylinder, the SAI80X950-S offers a drop-in dimensional replacement for other ISO 15552 cylinders of the same bore. Ensure your setup matches the G3/8 port size, PT tapered threads, and desired mounting accessory—such as an FA flange or TC trunnion. Note that standard double-acting cylinders do not hold position pneumatically; if the air supply is dropped, the load will drift unless an external pilot-operated check valve is installed.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI80 Standard Air Cylinder SAI80X950S FAQ
At an operating pressure of 0.7 MPa, this 80 mm bore cylinder generates 3518 N of push force and 2268 N of pull force. At 0.5 MPa, it provides 2513 N push and 2268 N pull.
Yes. The SAI80X950-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided your mounting hardware and G3/8 port connections align.
